Final answer:
In the scenario, Janice is offered long-term employment with a contract effective upon graduation, making it an example of job security.
Step-by-step explanation:
The given scenario where Janice, a third-year undergraduate student, is offered a permanent position at a publication house after her temporary employment is an example of job security.
Job security refers to the assurance that an individual will keep their job without the risk of becoming unemployed. This is evident as Janice is offered a permanent job contract to be effective upon her graduation, showing the company's intent to employ her long-term, which secures her a position in the future.
This practice can be contrasted with job rotation, where employees are moved between various jobs to increase diversity in their job tasks, job enrichment, which involves enhancing a job by adding tasks that increase responsibility, and succession planning, which is the process of identifying and developing new leaders who can replace old leaders when they leave, retire or die.
